FIREPLACE.

SPECIFICATION forming part of Letters Patent No. 538,959, dated May 7,1895.

Application filed August 17, 1894- Serial No. 520,585. (No model.)

Pennsylvania, have invented certain new and useful Improvements inFireplaces; and I do hereby declare that the following is a full, clear,and exact description of theinvention,

- which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to fire-places of that class or description knownas hollow back fire places, in which air from the exterior of thebuilding is introduced into said hollow back and heated by radiation,and then carried to the room in which the fire-place is located'or torooms adjoining or above the same.

The object of the invention is to provide an improved construction offire place of the above description which shall possess superioradvantages with respect to efliciency in operation.

In the accompanying drawings,Figure 1 is a front View of a fireplaceconstructedin accordance with my invention. Fig. 2 is a centraltransverse section of the same. Fig. 3 is a detail sectional view of theside wall. Fig. 4 is a horizontal section showing the draftregulator.Fig. 5 is a detail view showing the draft-regulator.

I able material.

In the said drawings the reference numeral 1 designates an ordinarychimney, and2 the flue for carrying off the products of combustion.

The numeral 3 designates the hollow back of the fire-place comprisingthe vertical walls 4, 4, inclined forwardly at theirupper ends, 5 thebottom and 6 the top. These walls may be made of tile, fire-brick, metalor other suit- The bottom 2, at the center is provided with a cold airflue 7, leading to the exterior of the building, and at its-top isprovided with pipes 8, leading'therefrom to the room in which thefire-place is located. It is also provided with a hot air flue 9, bywhich the hot air may be conducted to an adjoining room or to the floorabove.

The numeral 10 designates hollow side walls which may be made of thesame material as the back, and they are formed at top and bottom withhot and cold air openings, respectively.

On top of the hollow back Wall is a draft regulator, consisting of ahorizontally movable rectangular plate 12, having slots for the passageof the hot air pipes 8, and at its front edge is provided with a lug 13,with which a poker or other instrument may be engaged for moving theplate back and forth. When this plate is pulled out the throat of thefireplace or flue is contracted whereby the draft is decreased and whenpushed in it is enlarged and the draft increased.

The numeral 12 designates the grate, which may be arranged to burn coal,gas or any other fuel found desirable.

The operation will be readily understood. When a fire is made in thegrate, the air in the hollow back will be heated and escape into theroom through pipes 8, orinto other. rooms through fine 9, said pipes andflue being provided with suitable dampers. Fresh cold air will enter thehollow back through flue 7, and thus a constant circulation will be keptup of heated air from the heatingpipes 8. The hollow sides will also beheated causing a circulation therethrough, the .cold air entering thebottom openings and escaping through the top ones.

Having thus described my invention, what I claim is- In a fire place,the combination with the hollow back, having a cold air opening at thebottom, the pipes 8 leading to the room in which the fire place islocated, and-the hot air flue 9 leading to an adjoining room,'of thehorizontally movable draft regulator having slots for the passage of thepipes 8, substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoafiixed my signature in presence of two witnesses.
